ELECTRONIC CONTROL DEVICE

PROBLEM TO BE SOLVED: To provide a method of determining a preference order capable of recognizing that each process is completed by the time limit of the execution by taking into consideration the time limit of the execution which is the time when each process is to be completed in a control device built-in apparatus and the like for an automobile constituted of a central arithmetic device and a plurality of input circuits.SOLUTION: An interruption control device 114 receives interruption processes from signals of various sensors 112 via an input circuit 113. A process to be executed is determined from the received interruption processes so as to be notified to a central arithmetic device (a CPU) 115. The CPU executes the process, and instructs operations to various drive devices 117 via an output circuit 116 based on a process result. 【課題】中央演算装置および複数の入力回路により構成される自動車向け制御装置等の組み込み機器において、各処理が終了すべき時間である実行期限を考慮し、各処理が実行期限までに完了することを認識できる優先順位の決定方法を提供する。【解決手段】割込み制御装置１１４は、各種センサ１１２の信号から入力回路１１３を経由して割込み処理を受け付ける。受け付けた割込み処理の中から実行する処理を決定し、中央演算装置（ＣＰＵ）１１５に通知する。ＣＰＵは処理を実行し処理結果に基づいて出力回路１１６を経由して各種駆動装置１１７へ動作を指示する。【選択図】図１
